Global Catastrophe
An interesting concept: a global blackout caused by an EMP (electro-magnetic pulse).
It affects all electrical and electronic equipment. Communications are affected and planes fall out of the sky.
As people slowly learn what happened, they pull together as a family and as a neighbourhood to survive. It's a good thing this happened in the spring in the southern U.S. If it had happened in Canada during the winter, we'd be freezing to death. I also think there would have been more panic and lawlessness.
Suddenly, everyone has to do what the Amish have been doing all along; travelling by horse and buggy, growing their own food, burning or recycling their garbage, and sharing with their neighbours.
A murder in their neighbourhood makes them all suspicious of one another. The family learns some hard lessons about themselves and each other.
